Authorities are alleging in a search warrant that a Navy sailor based at Fort Bragg passed classified documents to an undercover FBI agent posing as a foreign intelligence agent, the Associated Press reports. In exchange, he was given cash.

AP reported that Navy Reserve Intelligence Specialist Third Class Bryan Minkyu Martin, 22, of Mexico, N.Y., was arrested last week, but has not been charged. He is, however, being held in the naval brig in Norfolk, Va.

AP, citing a search warrant filed in the Eastern District Court in North Carolina, reported that Martin received a total of $3,500 “from an undercover FBI agent in exchange for dozens of pages of documents that were classified either secret or top secret.”

At an initial meeting on Nov. 15, Martin told the undercover agent that his current assignment focused on Afghanistan and that he planned to work for the Defense Intelligence Agency, and would one day be very valuable, AP reported.
